Bringing together two generations of music fans, Robin Thicke and Chicago joined forces for a thrilling medley of hits on the 56th Annual Grammy Awards tonight (January 26).

The “Magic” singer strolled out onto the Staples Center stage to join the legendary band for “Does Anybody Really Know What Time It Is?” “Saturday in the Park,” and of course Thicke’s massive hit “Blurred Lines.”

Chicago’s frontman/keyboardist Robert Lamm told press he was looking forward to collaborating with Robin at tonight’s big show.

"We've performed all kinds of places in our long career. To finally be on the Grammys after not being around when we won [the band was on tour] is a real thrill."
